Simons MC, Hunt JA, Anderson SL. Trained to cut? A literature review of veterinary surgical resident training. Vet Surg 2024; 53:791-799. [PMID: 38816998 DOI: 10.1111/vsu.14110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 04/04/2024] [Accepted: 04/30/2024] [Indexed: 06/01/2024]
Abstract
A surgical residency trains veterinary graduates to a higher level of expertise in surgical procedures than is possible during veterinary school and prepares a resident to pursue board certification in surgery. The education of veterinary surgical residents has changed minimally since its inception in the twentieth century, and there are insufficient studies to determine if residency programs are producing surgeons with competence in each of the necessary procedural categories. The aims of this review were to report the current theory and methods used to provide surgical education to residents, to discuss the training most likely to create a competent, board-certified surgeon and to review assessment methods used during training. Several literature searches using broad terms such as "veterinary surgery residency," "veterinary surgery resident," and "veterinary surgical training" were performed using PubMed, CAB abstracts, and Google Scholar. Literature pertinent to theory, methods, training, and assessment of veterinary surgical residents was included. The reviewed literature demonstrated the need for research-based learning curves for specific procedures. Simulation training is known to facilitate deliberate practice and should be leveraged where possible to reach competency. The creation of validated assessment methods should be pursued as it enables assessment of competency instead of inferring its development from case logs. Understanding and supporting learner cognition and providing sufficient feedback remain important issues in the field. Surgical educators are urged to continue to search for innovative and evidence-based ways to train competent surgical residents.

Aly AM, Hayes GM, Boesch JM, Buote N, Korich J. Effect of surgical simulator training on student and live animal outcomes in a feline ovariohysterectomy teaching laboratory. Vet Surg 2023. [PMID: 37915112 DOI: 10.1111/vsu.14044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 09/06/2023] [Accepted: 09/28/2023] [Indexed: 11/03/2023]
Abstract
OBJECTIVE To evaluate the effect of training with a high-fidelity surgical simulator on outcomes of live animals and students participating in a feline ovariohysterectomy teaching laboratory. STUDY DESIGN Nonrandomized controlled trial. SAMPLE POPULATION Cats (n = 186) and students (n = 146). METHODS Live animals were paired with student surgeons. Outcomes for animals and students were evaluated over two consecutive years before (year 1: NO SIM) and after (year 2: SIM) the introduction of a graded student teaching laboratory conducted on a high fidelity surgical simulator. Live animal surgical times and postoperative pain scores using the Glasgow Composite Measure Pain Scale - Feline acute pain scale as well as self-declared student confidence were assessed and the scores of the two groups were compared. RESULTS The duration of the live animal surgical procedure was on average 6 min shorter in the SIM group (p = .04). A pain score triggering intervention (> = 5/20) occurred less frequently in the SIM group (n = 1/82) than in the NO-SIM (n = 16/104) group (p < .01). Similarly, rescue analgesia was administered less frequently (4/82 vs 16/104, p = .03) in the SIM group. Student confidence prior to the live animal procedure was higher (median = 7/10 [IQR = 6-8]) in the SIM group than in the NO-SIM group (median = 6/10 [IQR = 4-7]) (p < .01). CONCLUSION Surgical simulator training prior to live animal procedures improves live animal outcomes and student confidence. CLINICAL SIGNIFICANCE Surgical simulator competency should be considered a prerequisite to participation in live animal teaching laboratories. This would improve both animal welfare and the student experience.

Use of a Composed Simulator by Veterinarian Non-Experts in Minimally Invasive Surgery for Training and Acquisition of Surgical Skills for Laparoscopic Ovariectomy in Dogs. Animals (Basel) 2023; 13:2698. [PMID: 37684962 PMCID: PMC10487008 DOI: 10.3390/ani13172698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 07/12/2023] [Accepted: 07/17/2023] [Indexed: 09/10/2023] Open
Abstract
This study aims to assess the acquisition of surgical skills for laparoscopic ovariectomy (LOE) in dogs by veterinary surgeons with no experience in minimally invasive surgery using the CALMA Veterinary Lap-trainer simulator (CVLTS) in an experimental and analytical setting. Veterinary surgeons with no experience in minimally invasive surgery (MIS) (experimental, n = 5), and MIS experts (experts, n = 3) were evaluated. Experimental and expert group participants watched an instructional video (initial time) before practicing the LOE on uterine tissues and ovaries freshly reconstituted after elective ovariohysterectomy (initial time evaluation). Then, the experimental group practiced five training sessions on the composite simulator with permanent feedback and then performed the LOE again (final time evaluation). Surgical performances in initial and final evaluations were video recorded and further evaluated by three external MIS experts using Global objective assessment of laparoscopic skills (GOALS) and LOE-specific rating scales (SRSs) in a double-blinded schedule. In addition, a hands movement assessment system (HMAS) attached to the back of the hands was used to quantitatively measure completion time, angularity, and movement smoothness. Data were analyzed with one-factor ANOVA and Tukey's contrast test. No statistically significant differences were found between the novice group's performance after training and the expert group's performance according to the GOALS (p < 0.01) and SRS (p < 0.05) scores. Moreover, the novices had significantly improved time, number of movements, and angularity in the final time compared with the initial time (p < 0.05), with no significant differences compared to the expert group (p > 0.05). LOE training using a composed simulator resulted in significantly improved laparoscopic skills and time, number, and angularity of movements data, providing evidence of the usefulness and reliability of CVLTS in training LOE.

The Evaluation of a High-Fidelity Simulation Model and Video Instruction Used to Teach Canine Dental Skills to Pre-Clinical Veterinary Students. Vet Sci 2023; 10:526. [PMID: 37624313 PMCID: PMC10458249 DOI: 10.3390/vetsci10080526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 08/10/2023] [Accepted: 08/11/2023] [Indexed: 08/26/2023] Open
Abstract
In recent years, there has been an increased focus on the teaching of small-animal dentistry to veterinary students in order to address the recognized gap between dental skill training and the expectations of employers regarding the competencies of new graduates in this field. In this study, third-year veterinary students were trained in three canine dental core skills using either a high-fidelity model (Group A) or video instruction (Group B). An objective structured clinical examination was used to assess skill acquisition and questionnaires were distributed in order to assess student confidence and perceptions related to small-animal dentistry practice and related skills before and after the training. All results were compared between the two groups. Group A outperformed Group B in skill acquisition (p < 0.001) and there was greater improvement in skill confidence for Group A than Group B (p < 0.001). There was no statistical difference in perceptions related to small-animal dentistry between the two groups after the training (p ≥ 0.1). Group A rated their training experience more highly than Group B (p < 0.001). Although dental skill acquisition shows greater improvement when training is provided by models rather than video instruction, a blended approach to teaching dental skills is likely to be the best approach to optimizing dental skill acquisition.

Abstract
The limitations posed by the COVID-19 pandemic have been particularly challenging for courses teaching clinical and professional skills. We sought to identify how the COVID-19 pandemic has impacted the delivery of veterinary clinical and professional skills courses, including modifications to teaching and assessment, and to establish educators' perceptions of the efficacy of selected delivery methods. A branching survey was deployed to 35 veterinary schools in North America in March and April 2021. The survey collected data about curriculum and assessment in spring 2020, fall 2020, and spring 2021. Educators at 16 veterinary schools completed the survey (response rate: 46%). Educators quickly adapted curriculum to meet the requirements of their institutions and governments. Early in the pandemic (spring 2020), curriculum was delayed, delivered remotely, or canceled. Assessment methods frequently included virtual objective structured clinical examinations (OSCEs) and video-recorded skills assessments. Later in the pandemic (fall 2020, spring 2021), in-person clinical skills sessions resumed at many schools, often in smaller groups. Professional skills instruction typically remained virtual, as benefits were noted. Assessment methods began to normalize with in-person OSCEs resuming with precautions, though some schools maintained virtual assessments. Educators noted some advantages to instructional methods used during COVID, including smaller group sizes, better prepared students, better use of in-person lab time, more focus on essential course components, provision of models for at-home practice, and additional educators' remote involvement. Following the pandemic, educators should consider retaining some of these changes while pursuing further advancements, including improving virtual platforms and relevant technologies.

Abstract
In a veterinary medicine curriculum, students' hands-on practice is essential but is still considered one of the major deficiencies in veterinary schools in Europe. After theoretical and basic practical training, students, under the control of experienced veterinarians (supervisors), monitored the reproductive cycle of embryo recipients by transrectal palpation and ultrasound. To evaluate the skills of students, the question "Has she ovulated?" was posed when a dominant follicle ≥ 35 mm was recorded in the previous day's examination and a score of 1 or 0 was assigned in the case of a correct or incorrect answer (test palpation), respectively. Study 1 involved the retrospective evaluation of 3,509 test palpation records of 43 students (31 females, 12 males) and showed a statistically significant positive correlation between the number of test palpations performed and the proportion of correct answers. There was a statistically significant effect of the number of test palpations performed by each student, their gender, and the season on the correct answers. When performing > 50 test palpations, a statistical difference between gender was observed (p < .05). Study 2 involved the prospective evaluation of 687 records on 52 standardbred or thoroughbred recipient mares collected from nine right-handed female students. The different mares, breed, occurrence of ovulation on the left or right ovary, and the presence of one or more large follicle(s) per ovary had no effect on the correct answers (p > .05). Individual students' performances were statistically different (p < .05), ranging from 60% to 92%.

Abstract
Otoscopic evaluation using an otoscope is an important tool among the diagnostic modalities for otitis externa and is considered a core component of a canine patient's complete physical examination. Traditionally, otoscopic training in veterinary school involves using live dogs (i.e., laboratory dogs or dogs that are patients of the veterinary teaching hospital). While this approach has its advantages, performing otoscopic examination on live dogs presents several challenges: it requires adequate patient restraint, can cause stress to the dog, and can potentially cause trauma and/or injury to the dog's ear canal when performed by an inexperienced individual. Using an alternative teaching tool for otoscopic evaluation could overcome these challenges and improve veterinary students' learning experience. In this study, we investigated student perceptions of a novel canine teaching model for otoscopic evaluation in first-year veterinary students. The Elnady preservation technique was employed to create a realistic, durable, and flexible model for otoscopic training in a dermatology laboratory session in a first-year veterinary course. Student feedback was assessed on a Likert scale, and overall feedback indicated that students felt that the model was beneficial for skill building and removed many of the stressors incurred with using live animals when training in clinical skills. Most students stated that they would like to have additional similar models incorporated into training and would recommend these models to other students.

Abstract
Surgical skills are an important competency for new graduates. Simulators offer a means to train and assess veterinary students prior to their first surgical performance. A simulated ovariohysterectomy (OVH) rubric's validity was evaluated using a framework of content evidence, internal structure evidence, and evidence of relationship with other variables, specifically subsequent live surgical performance. Clinically experienced veterinarians (n = 13) evaluated the utility of each rubric item to collect evidence; each item's content validity index was calculated to determine its inclusion in the final rubric. After skills training, veterinary students (n = 57) were assessed using the OVH model rubric in March and August. Internal structure evidence was collected by video-recording 14 students' mock surgeries, each assessed by all five raters to calculate inter-rater reliability. Relationship with other variables evidence was collected by assessing 22 students performing their first live canine OVH in November. Experienced veterinarians included 22 items in the final rubric. The rubric generated scores with good to excellent internal consistency; inter-rater reliability was fair. Students' performance on the March model assessment was moderately correlated with their live surgical performance (ρ = 0.43) and moderately negatively correlated with their live surgical time (ρ = -0.42). Students' performance on the August model assessment, after a summer without surgical skills practice, was weakly correlated with their live surgical performance (ρ = 0.17). These data support validation of the simulated OVH rubric. The continued development of validated assessment instruments is critical as veterinary medicine seeks to become competency based.

Abstract
In the context of veterinary education, simulators are devices or sets of conditions aiming to imitate real patients and enable students to practice skills without the need for live animal use. Simulator use in veterinary education has increased significantly in recent years, allowing consistent practical teaching without reliance on clinical cases. This review examines the available literature regarding the use of simulation and simulators for teaching practical day one competences to veterinary students. Scientific databases were searched and 73 relevant articles were reviewed. The reviewed articles revealed that there are a number of simulators currently available to veterinary educators, that simulators can enhance student skills and provide an alternative learning environment without the need for live animal and/or cadaver use, and that they usually receive positive feedback from the students who use them. There appears to be a bias towards small animal simulators - however, some skills that are developed through the use of small animal or table-top models will be transferrable to other species. The majority of large animal simulators focus on bovine rectal palpation and/or pregnancy diagnosis. Further research is required to increase the repertoire of available simulators for use in veterinary education, in order to improve the practical skills of veterinary students and reduce the use of live animals and cadaver material for teaching purposes.

Abstract
Veterinary surgical education is improved by studying the relevant literature. The aim of this literature review was to report the theory and methods used to provide surgical education to veterinary students; to discuss the training most likely to create a competent general practitioner; and to review assessment methods for simulated and live surgeries. The literature reviewed demonstrates that new graduates are expected to perform small animal sterilization, dental extraction, onychectomy, abscess treatment, aural hematoma repair, and mass removal with little or no supervision. Students require repetitive practice to reach competence; some practice can take place in a clinical skills laboratory on models or cadavers. When training novices, distributing practice over a longer time improves retention, but months without practice causes skills to decay. Suturing skills may be taught on models at a ratio of 1 instructor per 10 students. Veterinary students require 6-10 repetitions of each small animal sterilization surgery to reach competence; however, learning curves for other surgeries have not been established. Assessment of surgical skills has been undertaken using objective structured clinical examinations (OSCEs) and observed model and live surgeries. Additional validated rubrics are needed in the field. Surgical educators are urged to continue to search for innovative ways to foster deliberate practice, assess skill, and provide feedback for students.

Abstract
An entrustable professional activity (EPA) model was used to assess the anesthesia and surgery competence of year 4 students during elective neutering procedures over 3 academic years (cohort A, cohort B, and cohort C). Two competence thresholds were defined by an expert panel, the minimum acceptable standard (MAS) and the standard expected at the start of final-year rotations (SFR). The assessment scheme performed as expected, and the median level of supervision achieved by students either matched or exceeded the SFR for all EPAs except one, which matched the MAS. Semester of assessment was associated with student performance, with more students in semester 2 achieving the SFR. In the EPAs assessing pain management, documentation, and patient discharge, cohort A was associated with reduced student performance; this could be explained by changes in the delivery of teaching that enhanced performance in subsequent cohorts (academic years). For all EPAs combined and for EPAs 3, 5, 6, 8, and 9, student performance at the SFR was associated with academic year. For all EPAs combined and EPAs 3, 8, and 9, there was a reduction in the proportion of students achieving the SFR threshold in each successive year. At the MAS, the only association for all EPAs combined was with cohort C. This progressive reduction in performance may have been related to the negative effect of decreased time spent at the neutering clinic and loss of feedback opportunities outweighing the positive effects of increased staff:student ratio and improvements in the preparative phases.

Abstract
Surgical skills are learned through deliberate practice, and veterinary educators are increasingly turning to models for teaching and assessing surgical skills. This review article sought to compile and review the literature specific to veterinary surgical skills models, and to discuss the themes of fidelity, educational outcomes, and validity evidence. Several literature searches using broad terms such as "veterinary surgery model," "veterinary surgical model," and "veterinary surgical simulator" were performed using PubMed, CAB abstracts, and Google scholar. All articles describing a model created and utilized for veterinary surgical training were included. Other review articles were used as a source for additional models. Commercially available models were found using review articles, internet browser searches, and communication with veterinary clinical skills educators. There has been an explosion of growth in the variety of small animal surgical task trainers published in the last several decades. These models teach orthopedic surgery, ligation and suturing, open celiotomy and abdominal surgery, sterilization surgeries, and minimally invasive surgeries. Some models were published with accompanying rubrics for learner assessment; these rubrics have been noted where present. Research in veterinary surgical models is expanding and becoming an area of focus for academic institutions. However, there is room for growth in the collection of validity evidence and in development of models for teaching large animal surgery, training surgical residents, and providing continuing education to practitioners. This review can assist with evaluation of current surgical models and trends, and provide a platform for additional studies and development of best practices.

Abstract
OBJECTIVE To evaluate the influence of instructor to student ratio on the effectiveness and efficiency of teaching suturing skills to veterinary students. STUDY DESIGN Prospective randomized study. SAMPLE POPULATION Second-year veterinary students (N = 121). METHODS Students were randomly divided into three groups to participate in four 2-hour skills laboratory sessions in which suturing of the subcutaneous tissue was taught by using a simple continuous pattern, suturing of the skin was taught by using continuous patterns, suturing of the skin was taught by using interrupted patterns, and suturing of hollow organs was taught by using inverting patterns. For each laboratory, the groups were taught by using instructor-to-student ratios of 1:6, 1:8, and 1:10 on a rotating basis. Students were surveyed at the end of each laboratory, and underwent individual performance assessments at the end of each laboratory session and again at the end of the semester in an objective structured clinical examination (OSCE). RESULTS For each of the four in-laboratory assessments and the OSCE, no difference in performance was detected between groups. When they were surveyed, students in all groups reported that there was an adequate number of instructors in the laboratory and that they received help in a timely fashion when help was requested (median for all groups = agree). CONCLUSION For students with prior surgical skills education and with the use of prelaboratory instructional videos, teaching at the 1:10 instructor-to-student ratio was efficient and effective. CLINICAL SIGNIFICANCE Good educational outcomes may be reached with a 1:10 instructor-to-student ratio or, potentially, fewer instructors, depending on the educational aids present in the laboratory and students' prior level of experience.

Abstract
The advent of the internet, and the technological innovations associated with it, have driven significant advances in surgical teaching and learning. The ease of access to information and the variety of online resources allow rapid sharing of surgical knowledge, promoting new teaching and learning patterns. Educational content from online platforms adds theoretical and practical knowledge to accelerate the learning curve and continuing education of surgeons. This study reviews how the advent of the Internet has influenced the teaching and dissemination of knowledge in veterinary surgery.

Annandale A, May CE, van der Leek ML, Fosgate GT, Kremer WD, Bok HG, Holm DE. Effect of a high-intensity one-week training programme and student-level variables on the bovine transrectal palpation and pregnancy diagnosis skills of final-year veterinary students. Vet Rec 2020; 187:e99. [PMID: 32978275 DOI: 10.1136/vr.105909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 07/28/2020] [Accepted: 08/10/2020] [Indexed: 11/03/2022]
Abstract
BACKGROUND To improve bovine transrectal palpation (TRP) and pregnancy diagnosis (PD) training, the effect of a high-intensity one-week training programme for veterinary elective students (N=59) with an interest in production animal practice was evaluated. METHODS Training consisted of exposure to rectal examination simulators, abattoir organs, theory materials and live cow PDs supervised by experienced large animal practitioners. Palpation skills were assessed before and after training using a validated TRP Objective Structured Clinical Examination (OSCE) in non-pregnant cows. Each student then performed PDs (n=12) on cows of known pregnancy status. Students' PD accuracy was measured as sensitivity and specificity, being respectively defined as the proportion of pregnant and non-pregnant cows correctly identified. RESULTS Students' scores improved from the first to the second OSCE (P=0.03), mostly as a result of improved ability to identify uterine symmetry/asymmetry and the presence/absence of a corpus luteum on the right ovary (P<0.01 and P=0.03, respectively). Overall student sensitivity and specificity of PD were 89.1 per cent (95 per cent CI 78.1-92.2 per cent) and 67.7 per cent (95 per cent CI 60.1-74.5 per cent), respectively. CONCLUSION This prospective cohort study describes a strategy to improve students' TRP skills with the potential to reduce training time and animal use at teaching institutions by outsourcing student training to private practitioners.
